Large iceberg breaks off from Grey glacier in southern Chile

Officials at Chile's Torres del Paine National Park, home to the glacier, said such ruptures were rare and had not occurred since the early 1990s

A large iceberg broke off the Grey glacier in southern Chile, authorities said on Tuesday, adding that the cause of the rupture was unclear.

Chile's Conaf forestry service shared photos on social media of the enormous block of blue-white ice, which measured 350m (1,148ft) long by 380m (1,247ft) wide, as it floated free in waters of a glacial lagoon near the southern tip of the South American continent.
